Separation of close-boiling liquids by fractional distillation in the presence of a low- volatility solvent or salt that selectively interacts with one or more components of the mixture, increasing the difference in vapour pressure of the sample components.

Note: If the separation solvent forms an azeotrope with one or more sample components the process is called „azeotropic distillation”.
